Pro-Grade Screen Recording in Your Browser
Обзор
OBS Studio, Loom, ScreenPal, Camtasia — these professional screen recorders cost $0-$300+ and need installation, accounts, or subscriptions. This Pro Studio brings the same essential capabilities to your browser: microphone + system audio mixing for voiceovers, webcam overlay (picture-in-picture) for tutorial-style 'narrate while you screen-share' videos, 4K resolution at 60fps for crisp tech demos, countdown timer before recording starts, pause/resume to break up takes, cursor highlighting, and a 10-recording history stored locally. No installation, no signup, no watermark, no upload — everything runs in your browser via MediaRecorder + Web Audio APIs.
Как пользоваться (по шагам)
- 1
Pick what to record
Screen + webcam, screen only, or webcam only. Mic + system audio mix is on by default — toggle off if you only want one source.
- 2
Tap record and run your demo
Use pause/resume as needed for clean takes. The picture-in-picture webcam stays draggable while you record.
- 3
Stop and review
Preview before downloading. Trim or re-record if needed — nothing leaves your browser until you save.
Как это работает
Combines three browser APIs: getDisplayMedia (your screen + optional system audio), getUserMedia (microphone), and a second getUserMedia call (webcam, used as a PIP overlay). When both microphone and system audio are enabled, a Web Audio AudioContext mixes them in real time into a single audio track. Video encodes to WebM with VP9 (or VP8 fallback) at your chosen resolution and framerate. Recordings save to localStorage as object URLs (lasting until tab close) plus a downloadable WebM file. Keyboard shortcuts (Space, S, P) let you control the entire session without touching the UI.
Когда пригодится
Recording YouTube tutorials where you narrate over screen-captured workflows. Creating product demos for marketing with face-cam in the corner. Asynchronous code reviews with audio commentary (Loom alternative for engineering teams). Online course content (Udemy/Skillshare lecture style). High-quality bug reports with full audio context. Anything you'd pay Loom or ScreenPal for — except free.
Частые вопросы
OBS is more flexible (scenes, transitions, custom encoders, streaming) and runs locally. This tool is faster to start (no installation), works on any device with a modern browser including Chromebooks and tablets, and covers 80% of standard screen-recording workflows. Use OBS for live streaming or pro film production; use this for everything else.
